What is a roots blower?
Roots blower is a positive displacement blower that uses two blade-shaped rotors to move relative to each other in the cylinder to compress and transport gas. It is a volumetric fan and has the characteristics of simple structure, convenient manufacturing and easy operation.
Working principle
The principle of Roots blower is to use two blade-shaped rotors to make relative motion in the cylinder to compress and transport gas. The rotor is driven by a pair of synchronous gears and moves in the opposite direction to push the inhaled gas from the air inlet to the exhaust port.
Application scope
Roots blowers are widely used in petrochemical, building materials, electric power, smelting, fertilizer and other industries. They are suitable for gas transportation and pressurization systems in low-pressure situations, and can also be used as vacuum pumps.

Roots blower uses
- Sewage treatment: Roots blowers are widely used in sewage treatment aeration. They increase the oxygen content in the water through forced air supply, promote the reproduction of microorganisms, and accelerate the decomposition of organic matter.
- Pneumatic conveying: In the powder conveying industry, Roots blowers are used as suction power and can transport small particles of powdery materials such as cement, grain, plastics and fly ash.
- Aquaculture: In aquaculture, Roots blowers are used to increase oxygen in fish ponds, increase the density of fish fry, and increase breeding output.
- Chemical Industry: In the chemical, electric power, gas and cement industries, Roots blowers can be used as desulfurization and oxidation fans, combustion-supporting pressurized fans, etc.
- Other applications: Roots blowers are also used in slurry mixing, fertilization fermentation, high-pressure air knives, vacuum suction, electroplating aeration and other fields. They are durable and cost-effective.
What are the parts of a root blower?
- Roots blower consists of five parts: casing, wall panel, impeller, oil tank and muffler.
- Chassis: mainly plays the role of supporting (wall panels, impellers, mufflers) and fixing.
- Wall board: mainly used to connect the casing and impeller, support the rotation of the impeller, and provide end sealing effect.
- Impeller: It is the rotating part of the Roots blower, which is divided into two blades and three blades. However, due to the many advantages of three blades, such as smaller air pulsation, lower noise, and smoother operation than two blades, it has gradually replaced the two-blade Roots blower.
- Oil tank: Mainly used to store lubricating oil used to lubricate gears and bearings.
- Muffler: used to reduce the noise caused by air flow pulsation when the Roots blower enters and exits.
How does a Roots blower work?
- 1.Roots blower consists of two gear rotors and a shell that mesh with each other. One gear rotor is the stator and the other gear rotor is the rotor.
- 2.When the rotor rotates, the gas is sucked into the air inlet of the Roots blower and pushed into the compression chamber between the gear rotors. The exhaust port discharges compressed gas from the compression chamber and pushes the object forward.
- 3.As the rotor and stator rotate, the compression chamber with decreasing volume moves to the exhaust side, and the gas is continuously compressed and then discharged.
- 4.After that, the gear rotor rotates to the new air intake position, the new compression chamber begins to compress the gas, and the compressed gas moves forward and is discharged.
- 5.This movement process continues, creating air flow to push the gas forward. In this way, the Roots blower achieves the purpose of compressing and discharging gas by removing the volume of the gas compression chamber.
